SPECIFICATION forming part of Letters Patent No. 4559,076, dated April 28, 1896.

l Application tiled .lanuary 31, 1896. -Serial No. 577,524. (No model.) I

To'all whom it may concern Be itV known that I, WILLIAM W. OONNER, United States, residing at Delaware, have invented certain new and useful Improvements in Means for'Automat'- ically Lubricating Vehicle-Axles; and I do declare the followin gto be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, My invention has relation to means for automatically lubricating vehicle-axles, and the y object is to provide a lubricating attachment th 15 of simple constructionadap ted to b e connected to theV hub and formed with an ,aperture'opening into the boreof the 'hub and adapted toconvey the lubricating substance to the surface of the spindle.-

have fully and clearlyiillustrated invention in wlierein` l y v Figure 1 a view showing the lubricator connected to the hub of a vehicle. Fig. 2 is my the' 'accompanying drawings,

25 a central vertical section' of the lubricator. A designates the lubricating-tube, the bore lof which is preferably made slightly tapering from top to bottom, as shown in the drawings. 4Midway between the ends f the tube is 3o an exterior annular shoulder orilange a, which 4sets down tight on the surface of the holding. vnut b. The upper exterior end of v,the lubricatingftube isprovided with screw-threadsc,

with which and close the tube and exclude4 all foreign substances. The lower exterior end of the lubricating -.tube is provided with screw- 4o threads g, which engage with the 'screwthreads in the interior of the holding-nut h set in the hub, substantially as shown. In

with engage the screw-threads d in cut n35 with ,the interior of the depending annular the capA f, which serves' to'cover the interiorof" the lubricating-tube is disposed a" valve h, consisting of a Astem z', terminating in an enlargement t at its lower '45 end, which lits loosely in the bore of the lubricating-tube and serves to regulate theiiow vof the lubricating material to the axle of the vehicle. The upper end of the valve h is pro- 5 vided with 'short spring ears or arms la, the 5o ends of which rest upon the top of the side 'walls of theflubricating-tube, as shown, the rise or descent of the valve being regulated by the increase or ldecrease of' the pressure upon the surface of the spring-'ears caused by 5 5 the tube.

To use my improvement, the oil or other lubricating medium is placed in the tube and e adjustment of the cap on j the cap screwed 1n place. The lubricating substance then descends and supplies the lubri- 6o cation essential to spindle.

Having thus described my invention, what I claim, and desire "to secure by Letters Pat-' ent, isr In combination with a vehicle-hub formed 65 1, an opening leading radially through the. hub, aholding-nut, provided with .interior screwthreads seated in said opening,l a 1ubricating-tube in the ho1ding-nut,'having a slghtlyftapering bore, and screw-threads on 7o its lower end to engage in the holding-nut,

springears at its upper end, and a screw- 75 vthreaded cap to `close the tube .and regulate the position of the valve, substantially as and for the purpose specified.

In testimony whereof I' `hereunto affix my signature in presence of two witnesses.
